Took my new shotgun to the range today. Ran like a champ right out of the box... much to the chagrin of the guys I know who bought alfalfas or derkas. 
As suggested, I put the heavy load gas ring in and it ran my federal XM127 00 buck through it 100%. It also ran all of my other ammo that I brought with me (federal and challenger target ammo) 100%.
Also tried the light load gas ring with the target ammo, and as expected: it ran everything 100%
The only downsides I've noted so far:
- If you put the gun on a table with the action locked open and ejection port up (ie: bolt release down), the bolt release is so oversized and awesome that it will release the bolt. You need to prop it up so the gun isn't resting on the bolt release when putting it on a the table (or put a chamber flag in it and let the bolt come forward)
- The chokes and iron sights started to come loose after a few rounds, but the irons were only hand tight and I didn't really give the choke that much of a tighten. I re-tightened both and they were fine for the rest of the day. The irons could probably use some blue locktite and I'll probably give the chokes a bit more oomph when tightening next time.
Completely happy with my purchase. Extremely happy it didn't require 100+ rounds to break in and start to become almost reliable
